Embryo transfer is a key procedure in assisted reproductive technology, specifically in in vitro fertilization (IVF). It involves placing one or more embryos, which have been fertilized in a laboratory, into a woman's uterus. The process begins with ovarian stimulation using hormonal medications to produce multiple eggs, followed by egg retrieval. The retrieved eggs are then fertilized with sperm, and the resulting embryos are cultured for several days. Once they reach an optimal developmental stage, selected embryos are transferred into the uterus using a thin catheter, often guided by ultrasound. After the transfer, hormonal support is provided to help prepare the uterine lining for potential implantation, and a pregnancy test is conducted about 10 to 14 days later to determine if the procedure was successful. This intricate process aims to increase the chances of conception, particularly for individuals facing infertility challenges.
